如何在IOS5上收到“消息接收通知”通知时获取消息

使用ios4.x我可以使用以下代码获取“kCTMessageReceivedNotification”通知时的消息

CTTelephonyCenterAddObserver( ct, NULL, callback,NULL,NULL, CFNotificationSuspensionBehaviorHold); 

if ([notifyname isEqualToString:@"kCTMessageReceivedNotification"])//receive message
    {

        NSDictionary *info = (NSDictionary *)userInfo;
        CFNumberRef msgID = (CFNumberRef)[info objectForKey:@"kCTMessageIdKey"];
        int result;
        CFNumberGetValue((CFNumberRef)msgID, kCFNumberSInt32Type, &result);   
        Class CTMessageCenter = NSClassFromString(@"CTMessageCenter");
        id mc = [CTMessageCenter sharedMessageCenter];
        id incMsg = [mc incomingMessageWithId: result];}

但是对于ios5我不能这样做因为incMsg是nil,所以我能做些什么来获取消息?

这是我发现的......

只需查看转储的私有API,看起来 ChatKit.framework 可能有所帮助。看一眼 CKSMSService.h

CKMadridService.h表示iMessage消息。

CKSMSService中有几种方法,我很快就试图调整自己的方法:

- (void)_receivedMessage: (id)arg1 replace:(BOOL)arg2 replacedRecordIdentifier:(int)arg3 postInternalNotification:(BOOL)arg4;

- (void)_receivedMessage: (id)arg1 replace:(BOOL)arg2 postInternalNotification:(BOOL)arg3;

但在iOS 5.0.1上我没有看到其中任何一个被调用(也许是我的错误?)。所以,我试图直接从sqlite SMS数据库中获取消息。注意...我没有构建完整的应用程序,注册通知。我假设你的代码让kCTMessageReceivedNotification没问题......它只是不再给你短信内容了。因此,如果您将以下代码放在通知处理程序中,您应该能够看到消息文本:

- (NSString *) mostRecentSMS  { 
    NSString *text = @"";

    sqlite3 *database;
    if(sqlite3_open([@"/private/var/mobile/Library/SMS/sms.db" UTF8String], &database) == SQLITE_OK) {
        sqlite3_stmt *statement;

        // iOS 4 and 5 may require different SQL, as the .db format may change
        const char *sql4 = "SELECT text from message ORDER BY rowid DESC";  // TODO: different for iOS 4.* ???
        const char *sql5 = "SELECT text from message ORDER BY rowid DESC";

        NSString *osVersion =[[UIDevice currentDevice] systemVersion];         
        if([osVersion hasPrefix:@"5"]) {
            // iOS 5.* -> tested
            sqlite3_prepare_v2(database, sql5, -1, &statement, NULL);
        } else {
            // iOS != 5.* -> untested!!!
            sqlite3_prepare_v2(database, sql4, -1, &statement, NULL);
        }

        // Use the while loop if you want more than just the most recent message
        //while (sqlite3_step(statement) == SQLITE_ROW) {
        if (sqlite3_step(statement) == SQLITE_ROW) {
            char *content = (char *)sqlite3_column_text(statement, 0);
            text = [NSString stringWithCString: content encoding: NSUTF8StringEncoding];
            sqlite3_finalize(statement);
        }

        sqlite3_close(database);
    }
    return text;
}    

现在,请确保此应用安装在 / Applications / 中。如果您只是构建此应用程序,并使用Xcode正常安装,那么由于应用程序沙盒,您将获得打开sqlite数据库的权限被拒绝错误。

我的代码段只获取最新的文本内容。 Here's an example of doing a little more with the database。查看QuerySMS方法。

此外,这是 sms.db link on the database format。你可以在那里找到你需要的其他东西。或者,只需将sms.db复制到您的计算机,然后使用Firefox SQLiteManager plugin之类的内容进行浏览。祝你好运!

我想在非越狱的iOS8设备上获取最后一条消息:

  1. CKDBMessage.h标题中获取ChatKit并将该文件添加到您的项目中。
  2. 注册kCTMessageReceivedNotificationCTTelephonyCenterAddObserver
  3. 使用此功能获取上次收到的消息的信息:

    void SmsReceived()
    {
        NSLog(@"GOT SMS");
    
        //open IMDPersistence framework
        void *libHandle =     dlopen("/System/Library/PrivateFrameworks/IMDPersistence.framework/IMDPersistence", RTLD_NOW);
    
        //make/get symbol from framework + name
        IMDMessageRecordGetMessagesSequenceNumber = (int (*)())dlsym(libHandle, "IMDMessageRecordGetMessagesSequenceNumber");
    
        // get id of last SMS from symbol
        int lastID = IMDMessageRecordGetMessagesSequenceNumber();
        NSLog(@"%d", lastID);
    
        // close (release?) framework -> needed??
        dlclose(libHandle);
    
    
        // get message object
        dlopen("/System/Library/PrivateFrameworks/ChatKit.framework/ChatKit", RTLD_LAZY);
        Class CKDBMessageClass = NSClassFromString(@"CKDBMessage");// objc_getClass("CKDBMessage");
        CKDBMessage *msg = [[CKDBMessageClass alloc] initWithRecordID:lastID];
    
        NSString *text = msg.text;
        NSLog(@"text: %@", text);
    }
